Recently we have proposed a table-top electron accelerator setup powered by THz pulses, in which the electron source was a krypton gas jet [4]. In our numerical model we have simulated the whole physical process and considered the ionization procedure combining with the THz induced electron acceleration. The model shows a significant influence of the ionization on acceleration mechanisms. © 2023 IEEE.}, keywords = {Electrons; MANIPULATORS; WAVEGUIDES; Acceleration; Physical process; Particle Accelerators; Electric fields; Ionization of gases; Krypton; Terahertz pulse; Table-top; Tera Hertz; Terahertz waves; Gas jet; Free electron lasers; Waveguide structure; plasma accelerators; gas plasma; Peak electric field; Electrons acceleration; Inverse free electron lasers}, year = {2023}, orcid-numbers = {Tibai, Zoltán/0000-0002-3196-7586} } @misc{MTMT:33872930, title = {Kompakt terahertzes részecskegyorsító elrendezés = Table-top THz-based electron accelerator setup}, url = {https://m2.mtmt.hu/api/publication/33872930}, author = {Balázs, Sarkadi and Turnár, Szabolcs and Kiss, Mátyás and Mátyás, Reményi and Anna, Bereghszászy and Almási, Gábor and Hebling, János and Tibai, Zoltán}, unique-id = {33872930}, year = {2023}, orcid-numbers = {Tibai, Zoltán/0000-0002-3196-7586} } @misc{MTMT:33872893, title = {Terahertzes impulzusokon alapuló elektronforrás}, url = {https://m2.mtmt.hu/api/publication/33872893}, author = {Sarkadi, Balázs and Turnár, Szabolcs and Hebling, János and Spencer, W.

In our calculations, we examined the acceleration with 300 GHz and 3.0 THz central frequency THz pulses with properties corresponding to common sources, and compared the Gaussian and Poisson spectral amplitudes and the associated time profiles of the electric fields. Our calculation takes into account both the longitudinal field and the spatio-spectral evolution around the focus. These aspects of the model are necessary due to the tight focusing and the duration towards a single-cycle of the THz pulses, respectively. The carrier-to-envelope phase (CEP) and the tilting angle of the coincident few- or single-cycle THz pulses must be tuned in all cases in order to optimize the acceleration scheme. We reveal additionally that electron beams with different final energies and different divergences can be generated based on simulated THz pulses having different Porras factors, describing the frequency dependence of the spatiotemporal amplitude profile, which may depend strongly on the method used to generate the single-cycle THz pulses.}, year = {2022}, pages = {32861-32870}, orcid-numbers = {Tibai, Zoltán/0000-0002-3196-7586; Jolly, Spencer W./0000-0002-5783-2081} }
